Officials are blaming at least 60 deaths on Harvey after the storm dumped metres rain on several Texas counties in a matter of days.
Many of those deaths were people drowning in flash floods or water-logged roads. But county emergency management departments across southeast Texas says they are also including people in their storm-related death totals who died from indirect complications of Harvey.
The huge dump of water loosened the ground around trees that fell into at least two homes in Montgomery County and on a car in Jasper County, accounting for some of the deaths.
Power outages knocked out electricity to medical equipment that several elderly people needed to survive. And officials said floodwaters also caused delays in responses to medical emergencies that resulted in deaths.
